Today I went to my university after a long time and tried to get access to the university network (eduroam) with an app called Wifi Helper (you have probably already heard about it). After a few tries my wifi suddenly stopped working and now goes off everytime I try to search for networks. Even now at home when I try to connect to my home network it doesn't work and my phone doesnt find neither my network or the networks from the neighbors. Also all the networks saved in my phone disappeared and I can't add any new network configuration.
To summarize:
-if I turn the wifi on the phone makes a scan for wifi-networks but doesn't find any
-the wifi goes off after 15-20 seconds
-I can't add new networks
I made a search in the forum but didn't find anything similar. I'm not 100% sure wifi helper caused this but I would say I'm 99,99% sure.
Until now I've tried uninstalling wifi helper, rebooting the phone, taking out the battery but nothing seems to help....so I would recommend not to use this app (if it's allowed to make such a recommendation).
I wish this has a solution and the wireless can work again. Hopefully someone can help me here or give me a couple of ideas (since this doesn't seem to be a common issue)
Edit: can someone tell me what files you have in /data/misc/wifi ? I checked in my phone with root explorer and I only found reg_code and wpa_supplicant.conf ...maybe wifi helper deleted something there.
Try a factory restet, its a bit of a pain but it should fix it
You mean to flash to the original firmware? X_X
I hope that's not the only way...
Maybe there's something missing in my wifi folder that I could compare with other phones.
I think wifi helper deleted almost everything in my wpa_supplicant.conf
This is all I got in there:
ctrl_interface=tiwlan0
update_config=1
can someone check if thats ok?
ctrl_interface=DIR=/data/system/wpa_supplicant GROUP=system
update_config=1
network={
Network info goes here
}

wifi helper screw-up your wpa_supplicant.conf, it happened to me 2.
Update the "ctrl_interface=DIR=/data/system/wpa_supplicant GROUP=system" like Bourbon Brain mentioned and your wifi will work normal again (hope you know how to do that).
Thanks for your help
I had to backup all my data to do the factory reset (I had totally forgotten about it ) and it took me quite a lot of time to set everything back to normal but it worked. After that the only difference I could find was in wpa_supplicant.conf so I guess if I had changed it to what Bourbon Brain and gpmg762 said it would have worked too (even much easier). Unfortunately I didn't wait till today
Glad to help regardless

hello all,
The last week I was using my wifi without problems in any wifi, I left the wifi on and after a while my phone shutdowned (lost charge). After this, my phone isn't connecting to any wifi (even those that it was able). I did a factory reset and he doesn't detect the networks.
I though I had the same issue with my x10 but editting the file didn't take effect on my phone. Tryed to delete the wpa_supplicant config file, edit it, downloaded various wifi fixers, and nothing seems to work. Could you help me?
Thank you

Hello there,
i follow all the steps here
http://forum.xda-developers.com/showthread.php?t=1019371
i edited the file, i've checked if the other files exists and all seems ok. I'm using cm7 on my X8 but i can notice some more battery draining but no n standard working.
Did i missed something?
i edited the ini file located in /system/etc/wifi and i only changed those values indicated in the post.
If i put the router only working in n standard i lost my connection.
Do you have anything i can check to see if i made a mistake somewhere?
Thanks in advance.
Hi there,
I had a similar problem, so thought I'd post the rather simple solution.
My wifi was working fine on my X8 with Floyo 0.25 (2.2.9) which I installed the other day. All of a sudden it just stopped working, constantly searching for a network and then saying disconnected. It only showed the saved connections I had, but none of the others (there are usually over 20 visible within my apartment block).
I tried all the usual things after reading on forums, deleting recently installed apps, reinstalling the system only using the advanced restore option in xrecovery, still no joy.
I got fed up, and just deleted my saved network for my router, and lo and behold all the networks that usually are there became visible again, and I could reconnect to my router, put in the password and it was working again.
I hope this helps someone else avoid 2 days of frustration!
Hi
I have a defy that has been happily running cm7.1 for a month or two. I am on holiday and have been using the defy to connect to wifi hotspots every 3-4 days, so have not updated anything or tinkered with settings etc.
The defy has just stopped scanning for networks, or finding wifi networks it has already used.
Turn on wifi and the defy does 'connecting' and then 'disconnected' every wifi network it has settings for is 'not in range' click on scan and it does nothing.
This is really frustrating as instead of spending 10mins in a wifi hotspot downloading stuff to read latter, I now have to search for internet cafes and spend an hour or two to keep on top of work.
Help would be appreciated, although I wont have any way of connecting the defy to a computer until i get home in a weeks time.
You could try forgetting every network and then press menu>scan
thanks, i have not deleted/forgotten all the networks, just the local ones. Sadly this has had no effect.
hey
Yup. ... even I had this problem once.
Solution - do a fresh flashing from the sbf and then the rom ... no nandroid restore .
Worked for me ( though I had to do the process twice )
Temme how it goes
I have a similar problem on GGL ROM (Defy Green Lens [Android 2.3.6]), which is a slightly modded version of the stock Defy+ ROM from Tmobile DE. Wifi worked flawlessly on all earlier ROMs (eclair, froyo, miui, cm7 and cm9). Toggling the battery settings to performance mode seems to delay the problem, but at some point the device loses the connection and scans for networks that other devices have managed to hold a stable connection to.

It happened me twice (with cm7). The only solution that worked for me was to delete (or rename) /data/misc/wifi/wpa_supplicant.conf and reboot. To do this, you need to have root permission and use root explorer/adb/shell emulator or even sshd
Keep in mind that you will have to put again all the passwords, so if you copy somewhere the wpa_supplicant.conf is better.
I read somewhere that performing a backup with titanium backup just regarding the wi-fi AP list (and restoring it) worked, but I never tried.
If that worked you could try to rename wpa_supplicant.conf to wpa_supplicant.conf.bak. Reboot. Delete newly created (by the system) wpa_supplicant.conf and rename wpa_supplicant.conf.bak to wpa_supplicant.conf and reboot. It should work.
Bye,
Peppe
PS: @yamandude it is clear that flashing an sbf will work, but that's like killing a mosquito with an atomic bomb
I had this problem too when I was on a holiday in a hotel that all my friends were happily surfing the internet with the hotel Wifi while I'm the only one struggling trying to connect. The Defy sees the Wifi/routers but wouldn't connect it no matter how I set or tweak the settings.. I end up restoring my backup via CWM when I got back home and solved it. The above work around would surely save a treat considering I wouldn't need to restore my entire backup.
Creating a new topic, because the other one is tagged as solved, but it doesnt solve my problem however.
So my wifi is not working, it's connecting to any wifi hotspot but not sending data thru that, which ends in failing loading any pages on IE, cannot download any apps from market and so on...
Anyway this is what I tried so far:
1. Flashed to stock rogers (also tried different Tango roms)
2. Did hard reset procedure via hardware keys (Format all Yes)
3. Did hard reset procedure via About menu
4. Did hard reset procedure via Samsung Diagnosis code sequence
5. Logged to my wifi network, everything looks fine at this point.
6. Opened IE and entered google.com:
"We're having trouble connecting to this webpage" (sometimes no error message but white page with scrolling bars appearing on touch)
7. Tried to access my wifi router via IP address (192.168.1.1) - the same results like above
8. Tried to ping my Samsung Fous IP (192.168.1.18) from my PC with success
9. Disabled wifi network security on home wifi router, the Focus still not working
Additionaly tried a method that fix issues with wifi after using latest wp7 tools, but it didnt help at all.
When using my providers APN there is no problem with opening pages on IE etc., but it's not Wifi.... Internet is also working if I have USB cable plugged in, but again it's not wifi.
Cannot use warranty, the phone is from the USA and I'm in Europe... without any warranty service.
What else I can do, maybe there are some diagnosis codes that can actually help with real diagnosis on what happened with wifi on my phone?
Hello again (from the other thread). For completeness, add the following:
- current OS version
- did/not use WindowBreak
- when did the problem start (if you can identify an event and OS version/revision) - or you noticed
There might be a test for wireless in the "diagnosis codes"... Good luck!
After you use the diagnosis fix, it might take some time, mine didn't work immediately but after some time, it detected my home network. But it seems you are able to connect but internet does not work, this is certainly issue with router/DNS settings in your phone, because I have faced these problems in iPhone, it might wrongly mapped to unreachable ip, but never faced this issue in Windows Phone, you might try changing the default gateway/dns settings, you should also reset your modem/router, and try basic setup before WPA/WPA2 setup

Hi there
Currently using 7.10.8773.98, (MAGLDR 2.0) but tried different versions, even vanilla pre-mango ones, they didnt work well with wifi on my phone either. I checked it at friends home wifi, which is totaly different network and routers.
I never used WindowBreak, never had to because my phone was already unlocked long time ago with ChevronWP7 application.
Noticed the problem about 2 weeks ago, but I didnt use wifi too much, so it could started much earlier. Last installed application was WP7 Tools 0.8 alpha, and all I did back then was using some built-in tweaks (3G?) if there is any, cant remember to be honest but for sure I wasnt editing registry or anything like that, I just play some games from time to time, cant event tell why I installed it, maybe because I noticed there is a new version. I cant tell because I never paid attention to it especially with rare wifi usage at a time.
I have isolated the problem I guess, and it's not the phone's fault. Something wrong with the main access point (Mikrotik) at my place. This is weird because everything is working just not on Samsung Focus. I digged thru many options and couldnt find anything that blocked or stuff like that. Well took it to totaly different place and another wifi network, and guess what - it's connecting to wifi with data flow...
Anyway consider this topic as solved.
Hello everyone,
Last week I upgraded my S4 to a brand new S5 on T-Mobile and currently it's stock and unrooted. It works great, except it won't automatically connect to WiFi. Every time I encounter a known WiFi it'll say Sign in Required. I'll press Connect and it'll then connect and function perfectly.
This smells like a software bug to me, but then I'd expect more posts on this topic (I didn't see any posts on XDA, and posts elsewhere were unhelpful).
What I'd ultimately like to know is if this is a hardware defect and I should get my phone replaced before it's too late, or if this is something that a software update (or rooting and flashing) will fix. Or of course it could be neither...
Thanks!
I have the same probblem and I am dying for a solution. I've spent hours googling and testing different things to no avail.
I am going to try to bring as much detail as I can, hopefully someone can pitch in.
Things I have read might work:
"forgetting" the connection and recreating it
Turning off and turning back on
Turning off, removing the battery
Turning off, removing the battery and the sim and waiting a minute (seems like voodoo to me)
Factory reset
I've tried everything, bar the factory reset which I am reluctant to do, specially when people's answers on forums said it wasn't a solution.
To try and shed more light, I would also add that:
It does this with any network (so it's not channel/router issue)
It does this consistently (and since I got my phone)
It finds networks, but just won't connect
It always connects fine if I pick the network (so it's not a distance/bad reception issue)
My phone is unrooted and stock and I have no weird apps (only popular/regular ones, social media, news, and so on)
My options are set correctly (notifications for open networks is checked and wifi is on)
I really hope someone can help as I rely on wifi a lot, and this is kind of a deal-breaker for me.
So I found a psuedo-fix here: http://forum.xda-developers.com/showthread.php?t=2723486
The key part being:
1. >Wifi >Advanced >Disable (uncheck) Smart network switch.
2. Forget connection, then establish connection again. Works no issues.

This has "fixed" it for me, but it also means I no longer have Smart Network Switch which is kinda annoying, albeit less annoying.
A true solution would be lovely.

Tried, didn't work for me.
I now have factory reset and let google reinstall all my apps.
Until now, auto-connect works.
The only thing I didn't do this time that I did last time is deactivate a bunch of samsung apps that come pre-installed.

I have been having the same issue. I can't get any answers either. It really is frustrating. I am going to keep trying to find out. When I called the T-Mobile store they said that I could bring it back w/in the 14 days & replace it and I may do that if I can't get an answer for the problem! If you happen to find out what the answer is PLEASE post and let us know! Thanks
My wife has the same issue with not auto connecting. She has a AT&T S5 that is not rooted....thanks to AT&T putting her in prison lockdown. I think it could be something with the last update because her phone used to auto connect just fine and now it doesn't. The strange thing is that she just now noticed it not connecting and she had took an update that was a few weeks ago or whenever it actually was and now we don't really know for sure if it's really just now an issue or has been since the update....imo I think it could be something with the update.
I have an S5 as well with no issues, but then again, I have the TMO that's rooted and carrier unlocked running custom rom.....thanks TMO for not being D***'s like at&t
Solution!
Long story short, there's a problem with Android and DHCP. Specifically, an IP associated with a router doesn't die when it should and attempting another connection goes back to this IP instead of using the correct (new) IP.
The good news is to forget the problematic wifi connection, head into /data/misc/dhcp/ and remove the files, reboot then connect to wifi. That flushes the DHCP lease information and life should be good.

use a program like "root explorer" or "ES file explorer" and navigate to your root folder ( / )
then follow the path /data/misc/dhcp/ , you will find the files i mentioned there.

Im reviving this thread, I have this issue also. And with my "unlimited" tmobile bandwidth of 2gb, this bug is completely screwing me over.
I quoted this post since you just claim its Android and DHCP, if thats the case, wouldnt all android phones just not work like the S5?

Hey I'm having the same issue, only with my work open wifi. The phone will be aware there is a wifi and it tells me to sign in. I go to the wifi settings and tell it to connect it does, but if it drops for any reason it won't automatically connect again, I have to go through the same thing every time.
I read this in a previous post:
"use a program like "root explorer" or "ES file explorer" and navigate to your root folder ( / )
then follow the path /data/misc/dhcp/ , you will find the files i mentioned there."
I have X-plore and went to the root/data folder, but there was nothing in the data folder - Do you have to be rooted for this to work?
Any help would be appreciated.

It works fine on my home network and others that I have a username and password for. The issue is WIFI hotspots at coffee shops and work and such, where I don't have access to the router settings.
I have an app that does an auto login when it recognizes that you need to sign in once it connects to wifi, and it works when I tell the phone to connect, but the phone will never connect automatically - I have to go into the WIFI settings and tell it to connect manually every time.
I have the 'Smart Network Switch" unchecked, and I have 'forgotten' and reconnected several times but it still happens.

I had a corrupt .keystore on my S5 and the fix I found by googling was to do a reset of the device.
Hey,
Sorry if this wrong spot to ask or anything, just let me know. Anyways have Note 4 Canadian. First time trying to root and followed guide @ http://galaxynote4root.com/galaxy-note-4-root/how-to-root-galaxy-note-4-using-cwmtwrp-method/ . Seemed to go fine, got to end rebooted, knox disabled on 2nd try etc... Seemed standard. But then it seemed that though I was connected to my wifi network nothing was working as far as internet. Couldn't use play store or browse. Have tried rebooting, tried wiping, factory reset, flashing to different image (tried http://forum.xda-developers.com/not...tecan-canadian-note-4-stock-root-rom-t2924941 as well) and nothing seems to be working. I've disabled/renabled wifi as well and all that. Connect fine, seems like there's a connection but just nothing works with it. If I disable wireless then my network data seems to work fine. Appreciate any help!
Solved it. Feel bad for asking now.
Anyways my solution was I need to change SSID on wifi network and fully reboot wifi while also forgetting connection on device. After that it seems to work.
